How to set 100% width to controls like Textbox and combo box...

      <table style="width: 100%;" border="1">
        <tr>
            <td>
                <ext:TextField ID="txt1" runat="server" StyleSpec="width:100%">
                </ext:TextField>
            </td>
        </tr>
        <tr>
            <td>
                <ext:ComboBox ID="ComboBox1" runat="server" StyleSpec="width:100%"></ext:ComboBox>
            </td>
        </tr>
    </table>

If i use the cls property to set the width .. its working textfield.

  <ext:TextField ID="txt1" runat="server" Cls="fillWidth" Flex="1" />

.fillWidth
{
    width:100%;
}

but the same fix is not working for combobox!
